    Biological Activity

    TPA023 (MK-0777) is a potent, α2/α3 subtype-selective, and oral GABAA receptor agonist with Kd of 0.92, 1.05 and 0.58 nM for α1-, α2-, α3-, and α5-containing human receptors.
    TPA023 (MK-0777) shows much lower (50- to 2000-fold) affinities for α4 and α6 subtypes (Ki= 60 and 418 nM, respectively).
    TPA023 (MK-0777) demonstrates anxiolytic-like efficacy and anticonvulsant activity in mouse pentylenetetrazole seizure model.
